SPECIFICATION' forming part of' Letters VPatent No. 566,514, dated August a5, 1896.

Application led October 31, 189 5 p T0 @ZZ whom, il; m07/ cormnvi:

Be it known that l, GEORGE J AMES GAU- BERT, manufacturer, of Richmond, in the county of Richmond and Province of Que-V bec, Canada, have invented certain new and useful Improvements'in Machines forliorm ing the Heels of Lamp-Chimneys; and :I do hereby declare that the following is a full, clear, and exact description of the same.

This invention has for its obj ect to provide a simple and effective machine for shaping the heels or necks of lamp-chimneys generally during `the process of manufacture, which act has hithertobeen performed by hand and requiring the services of a skilled workman, the Vmachine being also specially adapted for the shaping of the heels of chimneys of the construction shown in Canadian Patent No. 46,664, of July 26, 1894, to Walter E. Mayo, in whichia number of air-inlets are formed at the base by means of indentations in the edge thereof. j

To such ends, therefore, the invention consists in a machine in which the main feature is an expansible rotary interior spreader over which the outer end of the bulb of glass, while still soft and adhering at its opposite end to the blowpipe, is placed, the spreader being normally in a contracted .position until the bulb is in place and then expanded, the spreader,nevertheless,rotating permanently; a second feature consisting in the arrangement of a series of stationary pins or projections in such position relatively to the' spreader that they will coincide with the edge of the chimney-heel after having been fully acted upon by the spreader and `*by a subsequent pressure of the heel against them formj the depressions required in the special form of chimney above mentioned, while a third feature calls for the addition to the parts just described of an exterior rotary former acting in conjunction with the spreader to establish the thicknessof the heel, as well as to properly shape the outside surface thereof, these, with other features of detail and general construction of the carrying-frame and operating' parts, being hereinafter more par ticularly described,`and pointed out in the claims.

Having thus referred to the object and serai N10. 567,553. (Nt model.)

\ principle of my invention, I will now describe what Iconsider to be the most practicable embodiment thereof in an operative machine, reference being had to the annexed drawings, forming'a part of this specification, in which like symbols indicate corresponding parts and wherein- Figure l is a side elevation of the machine; Fig. 2, a front elevation thereof 5 and Fig. 3, a longitudinal vertical section of same, Fig. 2.

The frame of the machine as shown comprises a base-plate c and front and rear standards ct. co2, the standards providing bearings for an upper main operating-shaft b, which is tubular, and a lower counter-shaft c.

A driving-pulley d is carried by the main shaft bas well as a gearwheel e, intermeshing with a pinion c on the counter-shaft and through which the latter is operated. Y The main shaft b is made tubular in order to receive a spindle f, which extends through and projects beyond each end of same and which has a feather-and-groove connection fl f2 therewith to allow ,of its sliding longitudinally therein while rotated thereby.

The projecting rear end of the spindle f carries a pair of fixed collars g, between which a collar h with projecting pins h is held loosely in position so that such pins h can be engaged by the slotted and forked ends la of one arm of a bell-crank lever 7c fulcrumed at ,7a2 to the rear standard a2, the opposite arm .being suitably connected to a treadle or other usual operating means (not shown) for reciprocating the spindle in a frontward direction,

ably inade up of a central hub or carrier sec- -..tionn, having a screw-thread connection with the spindle, and a number (three being shown in this case) of centrifugally-movab'leiingers n', preferably of bell-crank lever form, with short and long arm portions and pivotally connected at the end of the short-arm portion to the central hub-section n so that the IOO ends of their longer and forwardly-projecting arm portions will converge and be normally in contact with each other at a central point in line with the axis of the reciprocating spindle.

Thus far I have described mechanism sufficient to produce a new and useful result if centrifugal force alone were to be relied on to throw the spreader-lingers outward, but I nevertheless prefer, in order to avoid running the machine at a higher speed than is necessary, to fulcrum the spreader-fingers, as at o, to lugs p projecting from the face of a disk p rigidly secured upon the front end of the main driving-shaft b, so that they will be operated positively as levers and their longer arms moved centrifugally by the frontward movement of the reciprocating spindle acting through the hub upon the shorter arms.

In order to make the indentations in the edge of the heel as called for in the special construction of chimney before mentioned, a stationary ring or face-plate q is situated in advance of the disk p (being preferably formed in one with the front standard through integral connecting-arms q) and having removably secured to its face by screws r a ring r with any desired number of pin projections r2 on its face in such a position as to be in line with the edge of the chimney-heel when spread to its full diameter.

The outer peripheral edge of the ring lr projects sufticiently beyond the edge of the stationary face-plate q to provide a journalbearing for the outer or exterior rotary former or litter for securing a uniformity of outside or ,peripheral diameters among the lamp-chimney heels of any particular size, and such outer former or litter is preferably constructed as follows:

A11 annular section or rin g s, having a flange s projecting frontwardly from its inner peripheral edge and gear-teeth s2 cut in its outer peripheral edge, is formed with a recess s3 in its rear face to iit over the journal-bearing formed by the edge of the ring r and is held in place, so as to be rotatable thereon, by means of a retaining-ring t, secured by screws t to the rear face of the annular section s and having its inner edge overlapping the rear face of the journal-bearing or ring r.

The outer former is rotated in an opposite direction to that of the inner spreader through a pinion u on the counter-shaft C, intermeshing with asecond pinion a', carried on a stubaXle u2, mounted in the front standard, which in turn intermeshes with the gear-teeth of the annular section s of such former.

In explanation of the operation of the inachine it may be stated that both the interior spreader and the outer former are permanently rotating in opposite directions, but with the spreader normally in its contracted position, and after the glass bulb has been blown to the required size and its outer end sheared off such outer end is introduced between the spreader and former and the spreader expanded by throwing the sliding spindle frontward, and when the heel is formed the bulb is pressed farther inward, so that the pins or projections r2 can make the required indentations in the edge thereof if the chimney is to be of the special form before mentioned.

To secure accuracy in introducing the bulb between the spreader and former so as to be truly concentric with the spreader, I prefer to use the guides or rests t, (indicated by dotted lines in Figs. l and 2,) in which the blowpipe with bulb attached can be placed, such guides being in proper position to secure the exact alinement of the blowpipe and spindle.

In order to provide for the forming of heels of different diameters, the interior spreader, the ring with the projections, and outer former are readily removable and interchangeable with others of various sizes.
